  • Publication number: 20240329168
    Abstract: Provided are an experimental apparatus and method for regulating and controlling the Zeeman transition of magnetic resonance. The method includes: generating a constant background magnetic field by using a magnetic shielding cylinder, a background magnetic field coil, and a constant current source, and controlling a Larmor precession frequency corresponding to the background magnetic field to be equal to a frequency of a sinusoidal signal output by a radio frequency signal source; adjusting the amplitude of a signal output by a radio frequency signal source of a pump-probe atomic magnetometer to set a radio frequency signal to be a ?/2 pulse or a ? pulse; and then controlling the radio frequency signal source to output a series of sinusoidal radio frequency pulse strings having the same initial phase. The Zeeman transition of magnetic resonance is regulated and controlled by adjusting the time interval between the radio frequency pulse signals.

  • Publication number: 20220271358
    Abstract: The present application relates to a method and system for determining parameters of battery pulsed heating. The reference potential of the anode of the lithium-ion battery is obtained in real time in the positive and negative pulsed heating process under various heating parameters. The relationship between reference potential and threshold potential indicates whether Li plating has occurred to the lithium-ion battery. When the reference potential is smaller than the threshold potential, the first heating parameters are adjusted to avoid Li plating and improve battery life. By recording the heating parameters when the reference potential is greater than the threshold potential, it can be ensured that the pulsed heating parameters have no significant impact on the life of the battery.

  • Patent number: 10657582
    Abstract: A service terminal, which is communicatively coupled to a remote server, communicates with an offline mobile phone located nearby via a short-range wireless communication protocol to complete a service request initiated by the mobile phone. The service terminal repeatedly broadcasts, via a short-range wireless transceiver, a service message to neighboring mobile terminals until after receiving a service purchase request message from one of the mobile terminals. The service terminal then suspends the broadcast of the service message and submits the service purchase request to the remote server and then receives a purchase confirmation message from the remote server. Next, the service terminal transmits, via the short-range wireless transceiver, the purchase confirmation message back to the user terminal.
